his application is a division of my -applica-.

tion filed October 26, 1925, Serial'No. 64,735. This invention relates to the art of coin control mechanism, wherein a coin deposited in a' machine will act as amedium for the operation of the machine from a source of power, and wherein a coin once operated upon by the machine to'vend a ware cannot-paused a second time. An object of my invention is'to provide a mechanism for the reception of a coin wherein it'becomes a medium for-T the transmission of power from its source to the operating members of the machine, and in the case of a vend' ing machine, is utilized to transmit power to the operating elements of the machine for the purpose of vending w'aresequivalent to the coin involved in the particular operation.

An object of myi'nvention is to provide a means for closing the coin slot of such mechanism against the passage of a coin therethrough after the insertion of a previous coin and during theoperation of the machina'and as illustrated herewith a vending machine, for the purpose of vending aware in-response to the injection of one coin, and the removal of the closing means upon the completion of a vending operation.

An object of my inventionis to-provide means for closing a coin slot against passage :of a coin therethrough upon the exhaustion of the wares to be vended, and the opening of the slot for the passage of coins when such wares are again available. a I r For the purpose of illustrating the adaptability of my invention to commercial use in conjunction with a 'vending'machine, I have illustrated the invention as being constructed-in conjunc tion with a drink'vending machine, wherein a supply of cups is maintained adapted to be singly separated and discharged to a position wherein they are filled with a drink for dispensing, upon the application of a coin to and within the coin slot, and the application of motive power to operate the machine; in the machine illustrated the source of power is through the manual op eration of a crank by the purchaser of thedrink. It being prearranged that there'are a less number of cups than the corresponding quantity of liquid to fillthem, the. machine isjassumed to be exhausted of wares when the supply of cups is exhausted, and to provide for the preventing of intending purchaser'slinserting coins into a machine with an inadequate supply of the wares it is supposed to v'en'd; I have provided the slot closing mechanism which is permitted to enter the a coin which is displaced from its operative PO51:

coin slot, upon exhaustion of the supply of cups, at a point where a coin which might be intended for insertion in the slot would only enter a portionof its breadth, thus providing the intending purchaser a meansof. retaining the coin,

rather than utilizing the conventional. method of dropping the coin in a slot, and then having the machine return the coin by mechanical means.v Y An object of my invention is to control mechanism wherein the slot closing device is normally in contact wtih the supply of wares to be vended. butto prevent injury to such wares upon their progressivemovement attendant upon the vendingoperation, I have provided that the slot closing mechanism be removed from contact with the wares during such progressive movement,and returned to a contact position upon cessation of such movement, thereby providing means for setting the slot closing mecha- I nism to close the slot immediately upon exhaustion of the wares.

An object of this invention is to positively discharge the coin into thejreceptacle therefor when it has served its purpose of forming a suitable 8O connection to operate the vending machine to vend'wares'. A

A feature of the invention is the employment of the coin to tension a spring, the force of which serves to knock the coin out of its carrier before 5 the vending mechanism delivers a ware.

7 Another object is to retain the coin in its operative position until the vending mechanism has been started into operation;

In this invention provision is made machine unless connection-between the crank and the operating'mechanism is made by an inserted tion when the crank passes a certain position, and such coin isthen displaced positively by' spring actuated means. a I J A further feature consists in means to bar passage of a coin, except when the hand crank initial or normal non-operative position.

It will be obvious that the coin-controlled mechanismis per se an invention and may be operated, if desired, separately from any'drink dispensing means or cup dispensing means, and in conjunction with any other mechanism, that it may be desired to operate thru a coin-controlled device. For such operation it is only necessary to extend the driven elements to connect with such other mechanism, and thereupon an inserted coin may be used as the'medium for transmitting power thru the driven elements to such connected mechanism.

Hence, the coin-controlled mechanism which is hereinafter described and claimed may be combined with many different kinds of devices, preferably vending machines wherein wares are dispensed presumably in amounts or quantities relative to the value of a coin inserted in the coin slot, and wherein this vending-type of machine is known as the coin-controlled type. In the drawings of the present application a coin-controlled drink-vending device is illustrated, designed to vend a drink consisting of two component parts; viz., a syrup and a charge of carbonated water delivered under pressure and mixed with said syrup by the machine at the time of its delivery therefrom into a cup provided for that purpose.

By reference to Fig. 1 it will be seen that the main portion of the machine consists of a metal frame having a base member 20 and a top member 21 connected by struts 22 at either side spaced apart and secured to said base and top members by cap screws 23.

The base memberZO is provided with a recess 24 which is open at the front side and has a hori zontal U-shaped forwardly open lip 25 upon which the released cup 26, in which the drink is to be vended, is supported to receive the drink mixture. a

A spout 2'7, see Fig. '7, is provided to take care of any drip, and a chute 28 located at the bottom of the recess 2 is provided to drop the used cups thru, and leads to a suitable receptacle, not

shown.

The base member 20 is provided with an extension upwardly of the recess 24 constituting the vertical passage 29 thru which the cups are delivered one at a time from a magazine above to the U-shaped lip 25, by cup dispensing means, hereinafter to be described, when the machine is operated to vend a drink.

The manually operated actuating mechanism comprises a hand crank 30, secured to a horizontal shaft 31 that is journalled in a supporting rib 32 at one side of the base member 20 and projects from the rear face thereof, and operates a coin carrier 33' rigidly fixed to the crank shaft 31 by pin 34; the coin carrier 33 is rotatably mounted upon a portion of shaft 35; the shaft 35 is rotatably journalled within the supporting web 36, a part of the rear section of the frame 20, as best shown in Fig. 6.

By referring. to Fig. 1 it will be seen that 1 have provided a coin slot opening at 37, in Fig. 2 the coin slot 3'. is shown in broken lines, in Fig. 6 it is also shown in broken lines, in Fig. 11 the coin slot 37 is shown partly in section, in Fig. 13 the discharge end of the coin slot 3'7 is illustrated} in section, in Fig. 16 the coin slot 37 is shown in its entirety, and in Fig. 17 it is again shown in broken lines; this coin slot 3'7 is adapted to receive and conduct a coin of a predetermined denomination to pay for one of the drinks as vended by a drink cup such as the illustrated cup 26 to the purchaser.

lhe coin slot 37 conducts a coin to the coin carrier33 where it assumes the position illustrated in Fig. 16, having come to rest within a slotted portion of the carrier 33 in a position to operate the driven elements of the mechanism by contacting the tappet 33 located between the limbs 40 and 41 of the carrier 33 and keyed to the shaft 35; the carrier 33 is preferably U-shaped and the open space 29 between the limbs 48 and i1 is of vhere'inafter to be. described."

' coinwill' contact the tappet 38 which, being keyed to the recited shaft 35, will ther'eby-actuatethe v driven elements of the machine. a

A coil spring 45, having one endsecured tothe web 36 and the other end to the carrier 33, is arranged to Yyieldingly' hold the coin carrier 33 against the side of the frame member in a position to receive from the coin slot 37 a coin to bridge the space 39 and operate the tappet 38 to rotate the shaft a v s The spring returnsthe carrier 33 with considerable force to its original position where it stops against theframe 20,- and there islikelihood of considerable wear atthe point ofcontacathus mis-alining the carrier 33 with reference to the coin slot 3'7,'and torprovide for proper adjustment against wear at thispoint I have provided means in the form'of adjustable screws 46 in the carrier 33 to contact the frame 20 so that when wear occurs adjustment'may bemade tore-aline the carrier 33 with the coinslot 37.

Upon the rotation of the crank 36 with a coin in proper position in the carrier 33, it will engage the tappet 38" and rotate the shaft 35 in one direction; the shaft 35, as best shown in Fig. 17, extends thru the-web 36 a sufficient distanceto have securedto it a mitre gear wheel 47, as best shown in Figs. 2, 6, 17 and 18, where it meshes with the 'gear48 secured to a vertical shaft '49 which is journalled in shaftbearing frame which is at- 'tachedto the frame 20; the vertical shaft 49 has further secured'to it a gear 51 (see Fig. 18); a horizontal shaft 52'supported byv bearings 53 attached to the frame 20 is provided at its 0p p'osite ends with gear wheels .54, one of which meshes with the recited gear 51 and the other with a gear wheel 55 secured to a'vertical shaft 56 which connects to the cup dispensing apparatus "By reference toiFig 2 it will be seen that the gear43 engages-a gear 57 mounted on a shaft 58 rotatably supported by'the bearing 59 and extending inwardly of the machine .a'sufficie'nt .dis-

master spring eccentrically connected by crank pin 65 to the revolvableniember 62 and" holding itin :a predetermined positiom-theoperation of the tappet 38 by the coin in the carrier 33 is against the resistance of the springs 63 and '64, such resistance affords a friction on the coin that tends to hold the coin in thecoin seat 43 during an operation; (The'coin enters thecoin seat143 from above whenthecarrier 33is in starting position, and. when the carrier 33 is oscillated it comes to a'point where it is inverted and thecoin would be drawn out by gravity if it were not for the friction caused by the resistance of the springs 63 and 64 which are given tension by the revolution of the member 62; when the pin '65,

' by which the springs 63 and 64are eccentrically connected to-the member. 62, comes to dead center as the springsswing across the axisv of the member 62, the resistanceof the springs to the advance of the tappet 38 under the'pressureuof the coin in the carrier 33 isso reduced that the friction onthe coin would be insufficient to hold the coin in position and it would drop out of the inverted carrier. 33, thusleavinggno connection between the carrier 33 and the tappet 38, so that operation of the machine; would not be car- ,ried on,

To overcome this difiiculty, thesha ft 58 ismade in twonalined sections connected .to each other by a coupling comprising the recited spring 60 which is secured to each of the .twosections of. the shaft 58, one section of which is secured to the recited member 62.

.Said intermediate spring 60 is of sufficient strength that when it is put under tension by the resistance of thetsprings 63 and'64 as: it

tion is sufficient not only to frictionally holdthe coin until: the dead center position is reached, but also-to suddenly thrust the member 62 onward after the springs 63 and 64 havepassed the dead center point; and the ;moment,the springs 63 ,and 64 have passed the. dead center point, theyoperate to instantly turn the revolvable member. 62 tonormal or initial position Where it comes to rest and is held insuch initial positionby the springs 63 and 64.

The springfiO isv so tensionedat the point at which the springs 63 and64 hold the member 62 at {rest that tappet 38 willbe just in front of the coin seat 43, so that whenever a coin is in the seat 43 and the crank-is turned,' thecoin in the coin seat 43 will contact the tappet 38and act to revolve it as before and cause the tappet 64 pass the dead center, thereupon suddenly completing the revolution ,of shaft 58 by spring action. When the member 62 is thus atfrest, the friction on the coin due to crank action and re-. sistance of the tappet 38 to the" advance of the approaches the dead center position, the'reaci '110 38 to turn the member 62 until the springs 63 and coin, is relieved, thus allowing the spring 45 to Whirl the carrier 33 roundinfreverse'direction andcausethe tappet 38 to positively kick the released coinout'ofthe coin seat. 43 in thefcar-v rier 33, which in that position of the crank is inverted, so, that the coin is positively thrown'out of such seatinto a coin receptacle.

Means are provided to'prevent' the insertion of a coin when thesuppl-y of cupsis exhausted, and

such means comprises a spring-actuated coinstopoperating' arm '66, best shown in Figs, 8, 10 and 11,-that is pivoted intermediate its ends at. 67, is provided at one end with a finger 68 constructed and arranged to "bepressed against the rim of a supported cup by means of a spring 69'secured to the frame 20 'by'means or" the" screw '70. The coin stopioperating arm 66ji's extended beyond the pivot 67' and is provided with the pin 71 adapted to be inserted into and across the coin slot 37 to prevent the insertion of a coin into the slot and stop it in a position whereby the purchaser may regain the coin without its passing chaser.

The friction of the finger 68 on the rims of the cups would prevent the cups from moving down, and it is necessary to withdraw the finger from the cups during the operation of dispensing the cup; this is effected by means of the operation of a cam-actuated pin 72, best shown in Figs. 8, 10, 11 and 17; this pin 72 enters the coin slot 37 from the side opposite to the recited pin 71 and is normally retracted by aspring 73 to hold it out of the coin slot 37; it is operated by means of a rocking arm 74 pivoted at to the frame 20.

and is actuated by means of engagement at one end by the cam 76 which is secured to the recited crank shaft 31 which oscillates with the handle 30; therefore, upon operation of the handle 30, the cam acts to insert the pin 72 into and across the coin slot 37, and is provided with sufficient travel to engage and move the pin 71, and thru it move the finger 68 out of engagement with a cup in the cup dispensing'device. When the pin 72 has been moved into engagement with the pin 71, it has passed transversely thru the coin slot 37 so that another coin cannot be inserted in said slot, and further provides a means for requiring the handle 30 to be in initial positionwhen a coin is inserted in the coin slot 37, thereby assuring correct positioning of the coin carrier 33 relative to the slot 37 whenthe coin is insertedj The cam 76 extends around the axis of the shaft 38 sufficientlyto hold the arm 74 and the pin 72 in operating position during an oscillation of the crank, whereby the pin 72 is contacting the pin 71 and retracting the finger 68 throughout all except a limited initial arc of the crank oscillation, so that while the cup dispensing elements are lowering a cup, the finger 681s held retracted from the projecting cup rim, but when the crank 30 is returned to its initial position, shown in solid lines in Figs. 1 and 1 1,,the spring 69 again presses the 'finger 68 against acup, which limits the movementof the arm66 'sufiiciently that the pin 71 does not enter the coin slot 37; when there is no cup present to contact the finger 68, the absenceof a cup permits the finger 68 to move a sufficient distance to rock the arm 66 and thus move the; pin '71 into and across the coin slot 37, thus providing a slot closing stop to prevent coins from being inserted into the coin slot The just described operation of providing a slot closer wherein is utilized the combination of the two pins 71 and '72, operates to provide a permanent stopping means at all times when there are no cups in the machine. to vend the drinks with, as the absence of the cups allows the pin 71 to enter, the coin slot 37, and should the crank 30 be oscillated the cam '76 operates to move the pin 72 intoand across the slot 37 Where it contacts and moves the pin 71, but upon its return movement the pin'71 follows the pin 72 and again is positioned across the slot 37, thus effectively preventing the passage of a coin therethru.

In view of the fact that the drink dispensing device herein illustrated is fully and completely described indetail in my recited co-pending appiication, filed October 26, 1925, Serial No. 64,735, of whichthis is a division, I will include but a brief description herein for the purpose only of illustrating a device with which the invention herein disclosed of a coin-controlled mechanism may be associated.

The drink dispensing mechanism is contained and supported by elements associated with the recited frames 20 and 21 and consists of a hollow casting 77, having a cover plate 78. A fountain tray '79, see Fig. 2, has a fountain or jar inverted thereon; A tube 81 leads from the tray '79-, being secured to the casting 77 by screws threaded into flanges 82. Said tube opens into an intake chamber 83, which, in turn, opens into a measuring or pump cylinder chamber 84. Said chamber 84 communicates with outlet chamber 85 thru a duct 86; best shown in Fig. '7. Said chamber 85has an outlet 87 that alines with a tube 88. A vent 89 at the top of chamber 85 admits air to'prevent siphoning of liquid from the 'jar :89. s

A rod 90 having a' valve 91 thereon extends thru the casting 77 and has at its lower end an anti-friction roller 92 that rests on a cam vface 93 formed on the periphery of the recited revolvable member 62 and is raised and low-.

ered thereby; Said cam causes the valve 91 to temporarily close the passage 94, which leads from the bottom of a pressure and float chamber 95v into the expansion chamber 96. Near the top of its upward stroke and after the valve 91 is seated, and the cam 93 is moving during the spring retracting portion of the revolution of the member 62, the rod 90 lifts a valve stem 97, having a spring 98 therearound, and unseats a pressure liquid inlet valve 99, thus permitting the pressure fluid to flow from the pipe 100' thru the cage 101 and thence into the chamber 95 while the outlet 94 is closed by valve 91.

A pressure tank 102, best shown in Fig. 6, is connected to the recited pipe 100 and has a shut off valve 103. valve 99 is open and the outlet valve 91 is closed,

the float valve stem 104 in chamber 95, see Fig. 1 T

7, is lifted by means of a float 105 attached thereto until said float, by means of a valve 106, closes a vent 107 in the cover plate'78; the said vent 107 communicates with the outer air to allow free escape of gas until the float 105 and the vent valve, 106 are lifted.

During the time that the inlet.

' Pressure chamber 95 communicates thru a port 108 with the recited pump cylinder chamber 84 having a piston 109 attached to piston rod 110 and at a spaced interval below the piston 109 and attached to the rod 110 is a second piston 111 for the purpose of measuring and pumping the syrup.

The expansion chamber 96 is provided with outlet tube 112 which extends to a point above and adjacent to the edge of a cup positioned on the U-shaped lip 25 that the liquid may pass thru the outlet 112 and be poured into a positioned cup; the tube 112 is so steeply aslant that the liquids discharged thereinto will flow out of the spout section with sufiicient velocity to shoot over into the positioned cup, but the spout terminates sufficiently behind the front rim of the drip cup 113 to allow any drops which may drip from the endof the spout todrainout thru the or the rim of the cup 26.

The cup dispensing device comprises-a maga-,

zine 114 mounted on and stationary to the upper frame 21, and has a circular cup-way above and axially alined with the passage 24 having a chamfered, internal flange ring 116 be-f low. which thin mutilated worm-rimmed or peripherally threaded revolublecupefeeding disks 117 are arranged to support a stack of nested cups 118 in the magazine 114. Two of said disks are mounted on shafts 119 revolvablyemounted in the upper casing 211 Whilethe third disk is mounted on the upper end of the shaft 56, the lower endof which has mounted on it the recited gear whee1,,51, theshaft 56 hasfurther secured to it the spur-gear which contacts and drives an annular gear 122 which engages and drives additional spur gear wheels 123 mounted on each of the shafts'119. The disks 117 are arranged withtheir spiral peripheries projecting into the cup-way115 tounitedly support the rim of the lowermost cup at onepart of the revolution and the spiral peripheralgrooves in said disks are, adapted, to receive the'rim of the lowermost cup and move such rim down and thus cause the .cup to 'drop into the vertical passage 24ywhen the disks are turnedto ,the appropriate position for supporting the next cup rim.

Preferably there are three; of such disks symmetrically disposed, as shown, and infixed relation torespective operating gears.

The source of power tooperate the cup-dispensing mechanism is the crank .30 and thru the variousrecited connections to the shaft 56 whichhas secured to it the recited spur gear 120 and also one of the disks 117, the spur gear 120 drivesthe annular gear 122 thru an idle gear 121, the annular, gear 122 meshes with the other spur gears 1120 on the recited shafts 119 to which are secured the other two disks 117 and the rotation of the annular grooves in the periphery of the disks is so timed that a cup will be dropped onto the lip 25 intime to receivethe mixed drink as it is discharged thru the outlet 112. As recited, the same movement of the crank .30 oscillates the cam 76 which actu'ates the pin 72 to enterthe coin slot 37, andcontact andyoperate pin 71 to'rock the arm 66 and thus remove the finger 68 from contact with the cup then residing in the-ring 116 at the time that the operation is commenced, thus removing any friction which might be caused by the contact of the finger with the cuppresent in the ring 116." a

As recited, the oscillation of the crank 30, 'assuming there is aucoin'in thecoin carrier 33 to complete connection, between the crank and the) driven elementsof the machine; brings theconnected mechanism to the point wherethe springs 63 and 64 pass dead center and the action of the spring 60 completes the revolution-of the-shaft 35 with a quick jerking'movement; advantage is taken of this accelerated'movement to complete the separation of the lowermost cup-from the stack of cups and force it downward with an accelerated movement at the instant of separation of it from the stack; this accelerated move-v ment or rotation of the disks 1 17 brings the supporting part of the edge of the disk under the flange or rim of. the next cup in the'stack as it drops down during the removal of the first cup, thus providin g'a continuous support for the stack of'cups, and further the accelerating movement 7 of the disks 117 at the separationlpoint insures the sticking of the lower cup to thenext cup abovefrom its having been pressedintoa stack by continuous confinement therewith. t

For the purpose of checking the monetary r.eceipts of the device in the form of the coins deposited in the coinreceiver against the numberv of drinks dispensed by the machine, I have pro videda counter 124 of conventional fcrmiocated adjacent the upper endv of oneof the shaftsrl19 whichis provided with a pin for, the operation of the counter 124, thus'recording one, unit for each rotationof the shaft 119, which, having one of the disks, 117;secured to it, will give. a count of one for each cup that has been separated from the stack-and used for dispensing a, drink, therefore, the number of times that the machine: isoperatedwill be recorded.

' Operation shown inFig, 1 whereby the coin carrier 33-wi11,

be alined with the coin slot 37 to receiveja coin,

and that the pins, 71 and 72 are withdrawn from the coin slot 37, the machine'is now in proper assembly to be operated. h r l 1 To operate the machine, a coin of the required denomination is placedin the slot 37 and runs downinto the grooves42 in the carrier 33 and seatsin the coin seat 43, providing-means for operatively connecting the shafts 31 and 35.

To operate the machine and thus complete the operative connection between the shafts 31 and 35, the crank 30 is turned in a clockwise direc- 2":

tion, which oscillates the coin carrier 33, having 'aco in in the coin seat 43, and brings the coin into contact ,with the tappet 38, and as recited the tappet 38 is secured to the driven shaft 35, and thus upon the operation of the crank 30the drivenshaft 35 is caused to revolve, together with iii) the gear wheel 47 secured to theopposite end of it qThe gear train comprising the gears 47, 48, 51and 54 are thereby rotated, as is also the gear wheel 57 which is secured to one end of the split shaft 58,- connected by the coupling spring 60, to the rotatable element 62, and upon :the'

actuation of this member, thesprings63and 64 are also operated, as well as the cam 93 which controls the-drink mixing and dispensing apparatus",

.The cup dispensing apparatus is operated thru the actuation of the gear 56 by the recited gear train and the several connected gears. operated therebyaand drops the lowermost cup of the stack down onto the lip 25, thus positioning a. cup

to receive the mixed drink from the outlet 112. The rotationof thercam 93 actuates the valve mechanism controlled by the rod 90, and thereby measures and mixes a drink which is provided thru the outlet 112and from that pours into the provided cup; the filled cup is now in position to be removed by the purchaser and consumed and the used cup may bedropped'thru the aperture 28 for disposal.

The-recited action of the=springs 63iand 64 to complete the rotation of the member 62'also com:-

pletes'the rotation of the recited gear train connecting-to the shaft 35 and to the cup-dispense "ing. mechanism, thus bringing them to the original or starting position; at thesame time the accelerated movement in the completion of the rotation releases the tappet 38 from its driven position relative to a coin in the carrier 33 and throws it around so that it strikes the coin from the other side, and in view of the fact that the coin at this point of operation may drop from the inverted carrier 33 by gravity upon removal of the contact of the tappet 38, the tappet may be able to move freely to complete its rotation, but should the coinnot be dropped out of the carrier 33 by gravity the tappet striking at its edge is designed to knock the coin out of the carrier 33, whereupon it will drop into a coin receptacle, not shown, and thus allow the carrier 33 to be reversed and oscillate back around to its original or starting. position under tension of the recited spring 45; the spring 45, during the initial movement of the carri r 33, is tensioned by the rotation of one end of it, and under this tension it is enabled to return the carrier 33 to its initial position, and consequently the attached shaft 31 and crank 30. r 7

As above recited, the initial movement of the crank 30 and shaft 31 have revolved the cam 76 a certain distance, and this movement has actuated the rocking arm 74 to insert the pin 72 into and thru the coin slot 37 to where it would engage the pin 71 and move it a sufiicient distance to rock the-arm 66 and thereby removethe finger 68 fromcontact with the cup rim of the lowermost cup of the stack, which as it is resting at the ring 116 is in a position to be contacted by the finger 68; this removal of the finger 68 as recited prevents friction" between it and a cup beingdispensed. The reversing of the carrier 33 which is keyed to the shaft 31 therefore reversely rotates the cam 76 and brings it back to its initial position wherein the rocker arm 74 will be removed from pressure against the pin 72 and by action of the spring 73 it is removed from its position within the coin slot 37, the consequent contact with the pin 71 thus leaving the coin slot 37 free for the passage of a coin, in so far as the operation of the pin 72 is concerned; the pin 72 has acted in two capacities during this operation, one as an actuator for the pin 71, and the second being as a slot closer during the period it resided within the coin slot 37, thus preventing a coin being inserted into the coin slot while the machine was being operated for drink dispensing purposes.

For further operation of certain elements of the machine, it is now assumedthat the supply of cups in the magazine 114 has been exhausted and therefore, there being no cup resting at the ring 116, the finger 68 under tension of the spring 69 will have traveled inwardly into the area normally occupied by a cup, and this movement will rock the arm 66, thus positioning the pin 71 within and across the coin slot 37,-thereby providing a positive slot closer preventing the insertion of a coin into the coin slot 37 far enough but that the intending purchaser may retain a hold upon the coin, and thus the coin will not pass into the machine when there are no wares to be vended; The crank 30 may be oscillated at any time'whether there be wares in the machine to be vended or not, but unless a coin has been droppedlinto the slot 37 and is properly positioned in the carrier 33, the moving'of the crank 30 will have no effect upon the other mechanism in the machine except to operate the rocking arm 74 which forces the pin 72 into and across the coin slot 37, and should there be no cups in the machine the pin 71 is normallyresiding across the slot 37 and the operation of inserting the pin'72 will only contact the end of the pin 71 and force it back across the slot 3'7 and the slot 37 will continue-to be closed, because the pin 72 will be forced into the position occupied by the pin 71 and upon its return the pin 71 will return across and close the slot 37, thereby, coins will be prevented from be-- ing inserted by the combined action of thetwo pins 71 and 72, which, when the supply of wares in the machine is exhausted, combine to act as a permanent slot closer until the supply of cups is replenished in the machine.

The beverage delivery mechanism is timed to operate during that portion of the movement of crank 30 which follows the delivery of a cup to the position to be filled. As this mechanism, separately considered,'is described and claimed in my original application and forms no part of this present application, a more detailed description of its action is omitted from this specification.

The cup deliverymechanism as such is timed to deliver a cup during the first portion of the operation of the crank 30, and as this mechanism, separately considered, is described and claimed in a co-pending divisional application, forms no part of the present application, a more detailed description of its action is omitted from this specification.
